Looks like my phone has a MT6739 which doesn't seem to be supported by the OP. Thanks for the efforts anyhow
First you need to find recovery partition. You can install Diskinfo app which can view all partitions without root. enable in Diskinfo settings all partitions. Then you will find recovery partition with path like mmcblk0pXX.
App currently doesn't work on Oreo.
To dump stock recovery, you can use root method for dumping.
open terminal emulator and run:
su
dd if=/dev/block/mmcblk0pXX of=/sdcard/stock-recovery.img
you will get stock recovery on internal storage.
For non-root method, you need to use SP Flash Tool.
Backing Up Using SPFlashTool.
1. Open the SPFlashTool folder and locate the file
Code:
option.ini
2. Open the file with notepad ++ or some other quality text editor and find the line
Code:
[ReadBack] ShowByScatter=false
Then change it to
Code:
[ReadBack] ShowByScatter=true
3. Save and close it.
4. Now reload your scatter file and go to the Read Back tab you will now see all the partitions that are in the scatter file.
My phone running android 8.0.1.. is that the reason why your tutorial not work ?

probably yes. But you can extract stock recovery from stock rom (look on internet, maybe you'll find it).
I dont have any scatter file for my phone.. i only find .tar.bz2 file.. i have no idea for this.. fyi, size of the file is 3gb
scatter is in .txt format and it have few kb. maybe try to extract it and see what you got.
hmm, that download tool is risky, it could be a virus. My advice is to wait for source code for your or for other device that have source code.
I think you need to find a way and unlock the bootloaderYou can flash it using SP flash tools, take scatter file from your ROM and then flash with SP tools...
Here is Fastboot Guide, but you can face adbd and large image error with fastboot.
Code:fastboot oem unlock fastboot flash recovery recovery-new.img
Thank u for your great job, i think the recovery we obtain is called "image-new.img" (and not "recovery-new.img" as it's mentioned in the screen instruction). I successfully get this recovery but don't know how to flash it ( because my phone is locked and not rooted "LENOVO C2- k10a40-" ( MT6735 ). HELP PLZ and thanks again .
